α-葡萄糖苷酶

Analysis Note

Protein determined by biuret.

Application

For the determination of α-amylase and the synthesis of various 1′-O-sucrose and 1-O-fructose esters

α-glucosidase is used for the determination of α-amylase and the synthesis of various 1′-O-sucrose and 1-O-fructose esters. It was also used in the measurement of glycosidase inhibition.^[2]

Biochem/physiol Actions

Hydrolysis of terminal, non-reducing 1→4-linked D-glucose residues with release of D-glucose.

α-glucosidase hydrolyzes carbohydrates by acting on 1,4-α linkages. Inhibition of α-glucosidase is a prominent target in the management of non-insulin-dependent diabetes mellitus^[1].
